USF geoscientists discover mechanisms controlling Greenland ice sheet collapse
Greenland’s more than 860,000 square miles are largely covered with ice and glaciers, and its melting fuels as much as one-third of the sea level rise in Florida.
Instability in Antarctic ice projected to make sea level rise rapidly
Images of vanishing Arctic ice is jarring, but its potential contributions to sea level rise are no match for Antarctica’s, even if receding southern ice is less eye-catching.
Researchers discover more than 50 lakes beneath the Greenland Ice Sheet
Researchers have discovered 56 previously uncharted subglacial lakes beneath the Greenland Ice Sheet bringing the total known number of lakes to 60.
These glaciers melt at your fingertips
Icy barriers began melting away at the close of the last ice age, easing human passage into North America.
New research shows an iceless Greenland may be in the future
New research shows an iceless Greenland may be in the future.
Study predicts more long-term sea level rise from Greenland ice
Greenland’s melting ice sheet could generate more sea level rise than previously thought if greenhouse gas emissions continue to increase and warm the atmosphere at their current rate, according to a new modeling study.
Jakobshavn glacier grows for third straight year
New NASA data shows that Jakobshavn Glacier — Greenland's fastest-moving and fastest-thinning glacier for most of the 2000s — grew from 2018 into 2019, marking three consecutive years of growth.
Melting small glaciers could add 10 inches to sea levels
A new review of glacier research data paints a picture of a future planet with a lot less ice and a lot more water.
Nuclear disasters could leave a lasting legacy of contaminants in glaciers
Nuclear disasters such as Chernobyl and Fukushima are known to have had an immediate impact on their surrounding environments and the people living within them.
North Atlantic warming hole impacts jet stream
The North Atlantic warming hole (NAWH), a region of reduced warming located in the North Atlantic Ocean, significantly affects the North Atlantic jet stream in climate simulations of the future, according to a team of researchers.
Melting glaciers causing sea levels to rise at ever greater rates
Melting ice sheets in Greenland and the Antarctic as well as ice melt from glaciers all over the world are causing sea levels to rise.
State of the Climate in 2018 shows accelerating climate change impacts
The physical signs and socio-economic impacts of climate change are accelerating as record greenhouse gas concentrations drive global temperatures towards increasingly dangerous levels, according to a new report from the World Meteorological Organization.
Cold water currently slowing fastest Greenland glacier
NASA research shows that Jakobshavn Glacier, which has been Greenland's fastest-flowing and fastest-thinning glacier for the last 20 years, has made an unexpected about-face.
Ice volume of glaciers worldwide calculated anew
Researchers have provided a new estimate for the glacier ice volume all around the world, excluding the Greenland and Antarctic ice sheets. Their conclusion: previous calculations overestimated the volume of the glaciers in High Mountain Asia.
Arctic sea ice loss in past linked to abrupt climate events
A new study on ice cores shows that reductions in sea ice in the Arctic in the period between 30-100,000 years ago led to major climate events.
Melting ice sheets may cause ‘climate chaos’ according to new modelling
Current international climate policies do not take into account full effects on global climate.
2018 fourth warmest year in continued warming trend, according to NASA, NOAA
Earth's global surface temperatures in 2018 were the fourth warmest since 1880, according to independent analyses by NASA and the National Oceanic and Atmospheric Administration (NOAA).
Greenland is melting faster than scientists previously thought
Greenland is melting faster than scientists previously thought—and will likely lead to faster sea level rise—thanks to the continued, accelerating warming of the Earth’s atmosphere, a new study has found.
Melting ice sheets release tons of methane into the atmosphere, study finds
The Greenland Ice Sheet emits tons of methane according to a new study, showing that subglacial biological activity impacts the atmosphere far more than previously thought.
Greenland’s ice is melting faster than it has in the past four centuries
Surface melting across Greenland’s mile-thick ice sheet began increasing in the mid-19th century and then ramped up dramatically during the 20th and early 21st centuries, showing no signs of abating, according to new research published Dec.
